' Application filed July 16, 1927, Serial Noe 206,205.

This invention relates to. window shutters or shields, and thegeneral object of the mvention is to provide a window shutter or I shield which, while permitting full ventilation of aroom, will prevent urglars from entering the room throughthe window and will prevent anyone looking into the room from the outside.

A further object. istoproyide a construction of this character whiclrwill fold up into a small space, which ma be readily handled and shifted into or out 0 position, and which is adapted to be raised to different heights and held at these different heights. 7

A still further object is to provide a device of this character including a plurality of V- shaped leaves or members which are flexibly connected to each other so that they may be held in spaced relation when the shutter-or shield is expanded or raised or folded into nesting relation when the shutter'or shield 1s contracted.

Another object is to provide means where- I by the lower end of the shutter may be detachablylocked in placein such position that the locks cannot be released by anyone exteraised. v

rior to the building.

Still another ob ect is to providelatches which detachably support the upper end of the shutter orshield v Still another object is to provide a shield or shutter of this character which may used as an awning in the sense that it Wlll permit the entranceof airbut will prevent the entrance of the sun whenthe shield is Other objects have to do with the details of construction and arrangement ofparts as will be morefully understood heremafter.

My invention is'illustrated in the accompanying drawings, wherein Figure 1 isa' face view of a shutter constructed 'n accordance with my inventlon Figure 2- is a vertical sectional view through a series of these Shutters, thesection being taken longitudinally;

Referring-to the drawings, 10 designates-a window casing of any suitablecharacter and including the sill 11, the jambs 12, andthe lintel13. The jambs 12 are formed with guides 14 which may be made of metal, wood or any. other suitable material but, as illustrated, I

these guides are formed of a hollow shell" 16 of metal with a wooden core disposed within the guides. Each guide is formed with the outwardly projecting rib 17 extending from top to bottom of the guide, and the lower end of each guide rests upon the sill'll. The

guides are formed at their up e r ends with two openlngs 18 constituting eepers, these openings being disposed one on each side of the rib 1 1.

Adjacent the middle of the guide tliere' is also formed two openings 18 or keepers which are disposed one on each side ofthe rib, At the lower endv of each guide there is a. double opening or kee er, designated 19,

disposed on each side 0 the rib 14. This opening differs slightly from the openings-18,

as theopenings 19 in each guide are rectan-' gular in form, 'while preferably the openings.

18 are somewhat semi-circular. :Operatin between-these guides are a plurality ofshaped leaves 21 constitut ng shutter or shield sections.

While I have illustrated a certain number of leaves, it will be understood. that the'number of leaves used in a window ma be more 1 or less, de endingupon the heig t of the window. ach leafQexcept the top leaf, is formed of a single piece of sheet metal bent to provide a bead 22 and'the downwardly diverging wings 23; Each head at its endsis longitudmally slottedat 24, these slots being for the reception of the guide ribs 14.1 Disposed within the head of each leaf,v except the to most leaf and the lowermost leaf, are two Each of these rod sections is longitudinally slotted, as at 26, from one end toward the other, and theseslotted ends of each pair of rod sections confront each other. These rod sections are oscillatable within the bead 22.

pairs of longitudinally slotted rod sections 25.

The outermost rod sections are riveted or otherwise attached to the beads but the innermost rod sections 25 have a limited sliding movement. Extending through a slot adjacent the endsof each bead are the links 27 l -which are pivotally connected to the lowermost member or section by means of'a rivet 28,- or other pivoting means, and these links 27 .extend'upward and inward and extend into the slot of the rhd section 25 of,

the leaf above to which they are pivotally "con- 'nected bypivot's28. The slots in these pintles 25 and 25 permit the links to fold up into nearly parallel relation to the-bead so that the inward toward each other to the position shown in Figure2 and the leaves will beheld air may pass between these leafsections,

vone immediately below the other in spaced relation;

, The leaves or shield sections are of such depth andthelinks are of such length that the upper edge of one leaf or sh eld section can never dro below the lower edges of the next adjacent s ield'section or leaf, and thus while as shown in Figure 5, a complete obstruction will be provided against anyone looking into the .room, as any straight view will be obstructed. Y

-As shown in Figure 2, each of the leaf sections fromtop to bottom is provided at the ends of each wing with the outwardly projecting lugs 29 which engage against the forward and rear faces of the guide 14 so that the leaf. sections are held from an inward or outward swingin movement. T e pintles 25 being oscillata ly mounted withinthe beads secure such flexibility in the connected 7 and interlinked leaves or shield sections-that there is'no danger of the leaves sticking or becoming jammed.

All of the leaf sections from top to bottomare alike, except the to and bottom sections. These slightly difler rom the intermediate sections in a manner which will now be stated.

The lowermost section 30, asshown in Figure 6, has the bead 22 and the wings 23, but in addition the wings 23 are intersected by a transverse partition plate 31 which, between the bead 22 and the partition plate, defines an irre ularly sided tube. Disposed within this'tufie is a coiled compression spring .32 which bears at its ends against two shiftable latch bolts33; Each of these latch bolts at its extremity is longitudinally slot-ted, as at 34, and rearward of the end of the latch bolt the underface of the latch belt at its ends is cut awa as at 35, so as to leave two separated bi s 36. The slot 34 is adapted to accommodate 'tlierib 14-and the bills 36 are adapted to engage within the lowermost openings 19 so as to hold't-he shield ina lowered sition. These bolts 33 are urged outward 3; formed in the partition 31 is the shank of an eye or finger piece 38. By pulling inward .endto the other.

the spring 32, and passing through a slot on these fi n ger pieces 38, both bolts may be retracted so as to disengage the lower end of the shield from the keepers 19 and permit the away so that no access can be had to these handles from'the exterior of the window. The uppermost lea'l 22 is alsoapproximately V- shaped but is formed tov provide two oppohandles 38, but the outer wing is not so cut 3 sitely disposed beads 40 separated from each other by an intermediate, upwardly curved,

longitudinally extendedportion '41 which is longitudinally slitted at its ends, as at 42. Disposed within the mediall disposed head 43 which corresponds to'the ad 22 .are the pintles 44, these pintles being connected by a longitudinally extending link 45 which is pivoted at its-ends in slots 46. Links 47 which c'orresp'ondto' the links 27 extend from .the pintle members '44 downward and outward to the pin tle members 25 of the subjacent leaf. The intles 44am longitudinally slidable within t e head or tube 43, the entire tube being open forthispurpose from one Disposed within the ends of the beads 49 are the twin latch bolts 48, these bolts being lon'gi- I tudinally slitted, as at 49, and being connected to each other by the outwardly'turned flanges 50 of eyes 51, these eyes extending up through bolts outward and the extremities of the bolts the slots 42. Springs 52 act toforcezthese plate-54 having therein alongitudinal slot;

55 and "alongitudi'nalslot 56 is welded in placelover the slot 42, thus preventing any removal ofthe bolts. Welded or otherwise attached to the uppermost leaf between the slots 55 are a series of connected eyes 57.

' It will be understood that a pluralit of eyes 51 may be connected to each pair of olts 48, if desired and that any number or eyes 57 may be disposed betweenthe latch eyes 51. Preferabl the leafnext tothe topmost leaf and any esired number of leaves below this are formed with an intermediate lug 58 that keeps the leaves from spreading or letting the parts bind. 1

It will be seen that this invention may be applied to windows of many different characters. The uppermost leaf may be disengaged.

openings 18 than are illustrated so that this under ordinary circumstances, about. two feet' from the lintelof the window, too high for any burglargto reach or anyone to look over. The'lowermost leaf may merel rest upon the bottom of the window sill-if esired and notv have any latches for holding it in place, but preferably it will have such a latch,-as I have illustra'tedyas thus this shutter is rendered burglar-proof, as no burglaror other person can raisethe lower end of the lower leaf from the outside. When-the shutter is expanded and the uppermost leaf is-engaged with the openings 18, the leaves cannot be either shifted up or down but will be held firmly in place, as illustrated in Figure 1, so.that air niay pass through into the room without, however, permitting anyone looking through the shutter into the room.

It will be seen from Figure 5 that the separate leaves nest very closely due to the factthat each leaf is rounded at its upper end so that the beads may set one upon another: Thus each leaf only takes a space of about when folded; While I-have illustrated a shutter or shield which is moved upward from the sill of the window, I do not wish to be limn ited to this as it is obvious that this shutter or shield could he made to disappear down through the window sill with the top shield resting upon the window sill. The shutter or shield could then be lifted, when desired,

through the window sill and lifted up to any extent required. The upper catch s own in 1 Figure 8is larger than the lower catch so that it will not interferewith the other parts of.

the curtain and it is somewhat wider than the lower catch so that it will not catch inthe holes into which the lower catch is supposed to engage. I

While I have illustrated certain details of construction and'arrangement of-parts, I do not wish to be limited to this, as obviously this may be changed in many ways .w1thout departing from the spirit of the invention as defined in the appended claims.
